IMPROVEMENT IN' RING-ES.

The Schedulereferredto. in these Letters Patent and making part of the saine.

To all whom 'it ma/y conce/rn:

Be it known that I, L. R. CHAJEMAN, of Grand Rapids, in the county of Kent, and State of Michigan, have invented a new and useful Improvement in -Window- Blind and Door-Hinges; and'I do hereby declare that the following is a full, clear, and exactv description there of, which will enable others skilled in-` the art to make and use the same, reference' being had to the accompanying drawings, forming part of this specification.

Figure 1 is a side view of awindow-shutter, to which my improved hinges have been attached, parts being broken away to show the construction.

. Figure 2 is a detail sectional view of the same, taken through the line x-:c, iig. 1, looking upward. Figure 3 'is a detail sectional view ofthe saine, taken through the line y y, fig. 1, looking upward.

Figure 4 is a detail under-side view of the catcharm.

Figure 5 is a detail top view of the eye-arm. Similar letters of reference indicate corresponding v parts. l

My invention has for its object to furnish a neat, simple, convenient, and reliable self-adjusting hinge, for doors, Window-blinds,i&c., which shall be. so constructed and arranged as to hold the blind, 'or door,

securely locked, when swung open, in such a way as 'to not only hold it securely, but also'prevent rattling; and

It consists in the construction and combination of the various parts, as hereinafter more fully described..

A represents the casing of a window, and

B represents the blind, or shutter.

0 is a plate, securely attached to the casing A.

D is an arm, 'formed solidly upon or securely attached to the plate G.

Through the forward end, lll, of the arm D, is formed a slot, or e101 `gated hole, for the reception of the ear, orpivoti11g-pf.:i, oi' the hinge, the rear side of said hole, or slot, being' hevelled, as shown in fig. 5, to accommodate the car? ,lor incline, formed upon said pin. Upon the fther end of the arm D is formed a projecting piu, i l bolt, (Zi, having a screw-thread cut uponits outer end, upon which is screwed a star-shaped catch-nut, E, several .washers being interposed between the catch-nut'E and the shoulder of the bolt di, so that the said nut may be easilyadjusted to hold the blind close up against the wall, and prevent rat tling. l

F` is a plate, screwed fast to the blind, B, and hav- G, formed solidly upon or securely at- -efect of whichis, when the blind is left free, to force the said pin to that end of the slot in the arm D which is opposite tol the said cam, orincline, and which, when the blind is pushed or drawn against said incline, causes the blind toA rise, lWhile. moving toward the Vother end ofthe slot, so as to i'ee the catch from the catch-nut E.

Upon the other end of the arm, or Hange G, is formed a-catch, I, which, when the blind is pushed or swung open, catches upon an arm ofthe catch-nut E, and locks' the blind open.

J is a Acup-shaped socket, securely attached to a plate, K, or having ears formed upon it, by means of which it is secured to the upper part of the casing, just above the rear upper corner of the bhnd, B.

L is an arm, one end of which is screwed fast to the blind, B, and the other end, which forms the pivotingpiu ofthe hinge., passes up into thecup-shaped socket VJ, and enters a recess formed in the bottom of said cup-shaped socket.

M is a coiled-wire spring, one end of which is attached to the upwardly-projecting part of the arm L, around which the said spring` is coiled, andV its other end is secured to the socket J, by being passed through a slit orfslot formed in said socket, or in any other conveulent manner.

lhe upwardly-projecting ,part of lthe arm L, and the recess in which it works, should be so constructed that the said arm may have a little play longitudinally, to allow the lower hinge to work freely.

I claim as new, `and desire to secure by Letters Pate-ntf- The combination of vthe plate C, arm D, having an eye, or slot, formed in one end, and a bolt, lli, formed upon the other end, star-shaped catch-nut E, plate F, and arln G, having a catch, I, formed upon one ehd, and having upon its other end an ear or pivoting-pin, H, with an ircline, h', formed upon its side, Witheach other, substantially as herein shown and described, and for the purpose set forth.

v L. R.. CHAPMAN.
